DETAILED DESCRIPTION

[0127] Throughout the following figures the same reference numbers will be used for matching parts.

[0128] FIG. 1a. shows a travel bag or transportation bag (100) according to an example. The travel bag (100) of this example comprises a main body (130) that may extend from a first end (1301) to a second end (1302) to define an extended configuration. The main body (130) may further be configured to adopt a compressed configuration (shown in FIG. 2). The travel bag (100) may further comprise a first lid (110) that may extend from an inner open end (1101) to an outer closed end (1102) and a second lid (120) that may extend from an inner open end (1201) to an outer closed end (1202).

[0129] The first end (1301) of the main body (130) may be connectable to the inner open end (1101) of the first lid (110). The second end (1302) of the main body (130) may be connectable to the inner open (1201) of the second lid (120). The first (110) and second (120) lids may be provided with connectors (170) in order to be connectable to the main body (130) to define the extended configuration. In some cases, the connectors (170) may further be able to connect the first (110) and second (120) lids, when the main body 130 adopts the compressed configuration.

[0130] In some examples, the connectors (170) may be selected from the group consisting of zippers, male-female connectors, magnets, pressure fitting, friction fitting, snap fit connectors, clip connectors, latches, buckle connectors, electronic connectors, rubber connectors, threads, clamps or combinations thereof.

[0131] The travel bag (110) may further comprise a handle system (150) that may be connectable to either an outer surface of the main body first (1301) and second (1302) ends or to the first (110) and second (120) lids. See dashed lines of FIG. 1a. In the example of FIG. 1a the handle system (150) is a strap. In alternative examples, the handle system may comprise more than one straps, one or more cords, ribbons, strings, belts, chains, ropes or bands.

[0132] An outer surface of the main body (130) may further be provided with drawings (140), texts, diagrams, textures, patterns, bar codes or logos. Alternatively, it may be coloured. In more alternatives, drawings and/or texts and/or colouring may be provided in the lids or combinations thereof.

[0133] The outer closed end (1102) of the first lid (110) may comprise a substantially flat surface that may be provided with e.g. an incense burner (116) and an area for ashes (114). In alternatives, a sculpture, a mirror, a board or combinations thereof may be foreseen.

[0134] FIG. 1b shows another example of travel bag (100) that may be formed in a single piece and comprises a main body (130) that may extend from a first end (110) to a second end (120). The main body (130) may be made of a substantially rigid or semi-rigid material and may comprise a plurality of folding lines (1300) that may be arranged substantially perpendicular to the longitudinal axis A-A of the main body (130). In the example of FIG. 1b, the main body (130) may be folded at a portion of the folding lines (1300) to define an extended configuration in which an elongated storage space for receiving a substantially elongated article is defined. In the example of FIG. 1b, only folding lines (1310-1316) are folded to define the extended configuration including an elongated storage space within the main body (130).

[0135] In the figure on the left, a yoga mat (200) is shown that is ready to be housed inside the elongated storage space. In the figure of the right, the mat (200) is shown to be housed inside the storage space.

[0136] In the example of FIG. 1b, the main body (130) is further provided with holes (135) that may be arranged in pairs. The holes may be configured to receive a back-pack handle system (150). In this example, four pairs of holes (135) may be provided. Two pairs may be arranged at opposite sides (along a direction perpendicular to the longitudinal axis) of the main body and at the same first height H1 along the longitudinal axis A-A of the main body (130). The other two pairs of holes (135) may be arranged at opposite sides of the main body and at the same second height H2 along the longitudinal axis A-A of the main body. The first height H1 may be closer to the first end 110 and the second height H2 may be closer to the second end (120) when the main body is in the extended configuration. In an arrangement of the main body in which the first end is a top end and the second end is a bottom end, the first height H1 is higher than the second height H2.

[0137] In the example of FIG. 1b, the back-pack handle system (150) comprises cords or ropes. In alternative examples, bands may be foreseen. The cords, ropes or bands may be used for a different use when the bag is not being used for transportation. In examples, jumping ropes, fitness bands, sculpting resistance bands, resistance bands or cords may be foreseen. The cords may further serve to laterally secure the mat 200 in the storage housing as shown in the figure of the right.

[0138] The folding of lines (1313-1315) may further define a further handle (172) at the first end (110) of the main body (130) in the extended configuration. The handle (172) may be form as a cut out on the rigid or semi-rigid material. In other examples, other folding lines may be folded and the further handle may not be present. See FIG. 4 or 10b.

[0139] In the example of FIG. 1b, a further bending line may fold a portion of the main body having a substantially oval shaped cut-out (165). The cut out may serve to secure the mat 200 when it is placed inside the storage housing and the fold portion provides stabilization to the main body. See figure on the right.

[0140] In the example of FIG. 1b, the main body (130) may further comprise a pair of foldable handles (1501) that may be configured to project out of its outer surface when the main body (130) is in the compressed configuration. See FIG. 3 (numeric reference 164).

[0141] In further examples, other number of folding lines may be folded as shown in the examples of FIG. 3 or 4 to define e.g. the compressed configuration. In the example of FIG. 3, the main body (130) may be made of e.g. cardboard. The figure of the right shows substantially no folded lines, the bag is not being formed yet and may function as a towel or mat. The figure of the left shows a compressed configuration of the main body (130) in which all folding lines may be folded. A pair of foldable handles (164) may further be provided configured to project out of the main body (130) outer surface when the main body (130) is in the compressed configuration.

[0142] FIG. 2 shows the example of FIG. 1a in three different configurations. The figure on the right shows the main body (130) in the extended configuration. The lids (110) and (120) may be respectively connected to both ends of the main body (130). In this example, a stiffening member (134) may further be provided at both ends of the main body (130) to aid connecting the ends with the lids (110) and (120). A zipper (136) may be provided at the open ends of the lids (110, 120). A matching zipper may be provided at the stiffening member or at the ends of the main body when no stiffening member is provided. The zipper (136) connecting the first lid (110) with one end of the main body (130) is also shown in the cross-sectional view of FIG. 15. In alternative examples, other mechanical closing systems may be foreseen. The stiffening member (134) is also shown in the cross-sectional view of FIG. 15.

[0143] In this example, the strap (150) may be in the form of a bandolier and may be connected to the second lid (120) through a mechanical coupling such as a button/eyelet coupling (156). In alternative examples, other mechanical couplings may be foreseen such as clips, hook-and-loop strip, tie strings, Velcro or similar.

[0144] Further in this example, the main body (130) may be made of a flexible and foldable material and may further provided with one rod (138) describing a substantially helical shape around the flexible and foldable material to allow instant twist and fold of the main body (130). In this example, the natural relaxed state of the rods may be close to their shape in the extended configuration. To obtain the compressed configuration, the body is compresses, and the various turns of the helical rod are pushed closer together.

[0145] In the example of FIG. 2, the figure in the middle shows an intermediate configuration in which the main body is partly compressed. In this case, a storage housing (not shown) may be defined within the main body and the lids. The storage housing having a volume that is lower than that of the elongated housing of the extended configuration and that is bigger than that defined within the two lids when the main body is in the compressed configuration. A further mechanical coupling may be provided to lock the bag in this intermediate configuration.

[0146] The figure on the left shows that the two lids (110, 120) may be connected to each other, to define the compressed configuration. In this example, the compressed main body (not shown) may be housed within a storage housing that may be defined by the lids (110) and (120) connected to each other.

[0147] The example of FIG. 4 differs from the example of FIG. 1b in that the further handle has been removed. Furthermore, the cords have been replaced by a jumping rope (166). The final shape is also slightly changed.

[0148] In this example, the figure of the bottom shows the extended configuration and the figures of the top the compressed configuration. In the figure of the bottom, the first end (110) of the main body (130) may be made by merely folding lines (1311-1313). And an outer surface of the main body may incorporate texts or diagrams (142).

[0149] In the figure of the top, the main body (130) may be in the compressed configuration, acting as a secondary bag for smaller articles, and the jumping rope (166) may be separated from the bag (and used). A portion of the outer surface of the main body may further be used as a notepad (144) or as a digital screen. A further band or strap (173) may be provided to aid maintain together the main body in the compressed configuration. And the substantially oval shaped cut-out (165) becomes a handle.

[0150] FIGS. 5a-5d show four examples of overall appearances that a travel bag in the extended configuration may adopt. FIG. 5a shows a prismatic configuration having a square cross-section. FIG. 5b shows a prismatic configuration with a cross-section having a pentagonal shape. FIG. 5c shows a bag with a cross-section having a hexagonal shape. And FIG. 5d shows a bag with a cross-section having a circular shape. Other polygonal or rounded cross-sections may also be foreseen. The overall appearance of the extended configuration may thus be considered substantially tubular.

[0151] FIG. 6 shows the travel bag of FIGS. 1a and 2 with a mat (200). The sequences of figures from left to right show the steps for rolling the mat and introducing it inside the bag to get ready for transport. The first step starts with the bag in the compressed configuration. In this configuration an incense stick (1161) may be placed in the incense burner as explained in connection with FIG. 1a. The first step may comprise rolling up the mat (200). See arrows F1. Once the mat is rolled up, the second step may comprise starting expansion of the main body. See arrows F2. When the main body (130) is in the extended configuration, the third step may comprise opening the first lid 110 by unzipping zipper (136) and introduce the folded mat (200) inside the elongated storage housing defined in the extended configuration (explained in connection with FIG. 1a). See arrows F3. The last step may comprise closing the first lid (110).

[0152] FIG. 7 shows the travel bag of FIG. 4 with a mat (200). The sequences of figures from left to right show the steps for rolling up the mat and introducing it inside the bag to get ready for transport. The first step starts with the bag in the compressed configuration and the strap/rope or cords in a released configuration, i.e. being usable e.g. as a jumping rope as explained in connection with FIG. 1b. This compressed configuration may allow storage or transportation of other items such as shoes (4000), cell phones (4001) or other items that might require storage while practicing yoga or related activities. The first step may comprise rolling up the mat (200) as explained in connection with FIG. 6. Once the mat is rolled up, the second step may comprise starting expansion of the main body. To do this the strap (173) needs to be unfasten and the rope may be provided through the eyelets. When the main body (130) is in the extended configuration, the third step may comprise introducing the folded mat 200 inside the elongated storage housing defined in the extended configuration (explained in connection with FIG. 1b). When doing this, care should be taken to introduce the mat within the oval cut-out (165) as explained in connection with FIG. 1b, which may also act as a handle in the compressed configuration.

[0153] FIG. 8 shows a person carrying the bag of FIG. 1a, 2 or 6 in the extended configuration being used to transport an elongated element, e.g. a yoga mat. In this example, the handle system (150) may be a belt (154) that may comprise rings (169) to adjust its length.

[0154] FIG. 9 shows a person using the bag of FIG. 8. The person may actually be using the mat (200) for practising yoga while the bag may be in the compressed configuration in which the incense burner (116) may be used. Furthermore small items such as keys, mobile phone, or purse may be housed inside the storage space defined by the two lids (110) and (120) being fasten to each other defining the compressed configuration.

[0155] FIG. 10a shows an exploded view of the travel bag of FIGS. 1a, 2 and 6 in the extended configuration. In this exploded view the connector (170) of the first lid (110) may comprise a stiffening member (134) with a zipper (136) and the main body first end may also comprise a stiffening member (134) with a matching zipper (136). The strap (150) may be in the form of a belt (154) and may be connected to the main body through a mechanical detachable coupling such as a button/eyelet coupling (156). In alternative examples, other mechanical couplings may be foreseen such as clips, hook-and-loop strip, tie strings, Velcro or similar. The belt (154) may be made of textile, leather or similar. The belt may be connected to the main body with a fixed stitching (152) or similar. The stitching (152) is also shown in the cross-sectional view of FIG. 15. Having one end fixed and the other detachable ensures that the belt remains fixed to the main body but does not hinder compressing it into the small storage housing in the compressed configuration. In alternative examples, other ways of attaching the belt or strap to the main body may be foreseen, e.g. the strap may comprise two fixed stitching at both ends of the main body or two mechanical joints buttoned type or clip may be foreseen. In these cases, the strap may be released from the main body and may have a further use, e.g. jumping rope, resistance bands. Alternatively, two slings or ropes may be provided such that the bag can be converted into a back-pack.

[0156] FIG. 10b shows an exploded view of the travel bag of FIGS. 4 and 7 in the extended configuration. The strap (173) for holding together the bag in the compressed configuration is identified and is attached to the main body (it has no use in the extended configuration). A further tongue (171) is shown at the second end (120) which aids completing the folding and maintaining its folded condition in the extended configuration

[0157] FIG. 11a shows the example of FIG. 1b (figure on the left) in the extended configuration in which the pair of foldable handles has been removed.

[0158] FIGS. 11b-11f show further examples of the travel bag of FIG. 1a in the extended configuration.

[0159] FIG. 11b shows an example in which the main body (of the travel bag) as such is left out. This way, the travel bag may comprise only a first lid (110) and a second lid (120). This example may be used for transportation of rigid or semi-rigid elongated articles such as the yoga mat in a rolled condition. The first end (110) that may extend from an inner open end to a closed end and the second end (120) may also extend from an inner open end to a closed end. The rolled mat may be inserted into the inner open ends of the first (110) and second (120) lids.

[0160] The lids (110) and (120) may be provided with fastening connectors (170) able to connect each other when the mat is removed to define a compressed configuration.

[0161] In this example, the inner open ends of the first and second lids may have a geometry that may be defined as a function of the substantially rigid or semi-rigid elongated article to be transported, e.g. the rolled mat, such that the rolled mat can be snap fitted inside the inner open ends. In alternative examples, the inner open ends of the first and second lids may be provided with mechanical-based fastening elements able to fix the rolled mat (or any other elongated article) to be transported to the first and second lid.

[0162] A handle or strap (174) may further connect the first lid (110) to the second lid (120) to provide a handling system and more rigidity or stability to the bag in the extended configuration. A handle system (150) may be provided in e.g. the first lid (110) (or in the second lid or in both lids).

[0163] FIG. 11c and FIG. 25 or 26 show an example in which the main body may be made of a rigid or semi-rigid foldable material such as cardboard, plastic, rubber or alike. In these examples, the main body may comprise a plurality of folding lines that may comprise a combination of triangles forming a faceted-like surface so as to fold like an accordion or origami when the main body is in the compressed configuration. The main body may be connectable to a first and second lid substantially as explained in connection with FIG. 1a, 4, 6 or 10a. Alternatively, the folding lines may be a series of parallel lines that may be arranged substantially perpendicular to the longitudinal axis of the main body so as to fold like an accordion when the main body is in the compressed configuration.

[0164] The example of FIGS. 25 and 26 differ from that of FIG. 11c in that the main body and the lids may be made from a single piece. A further difference is the shape of the lids. In the example of FIG. 25 the lids are hexagonal whereas in the example of FIG. 11c the lids are circular. Other shapes may also be foreseen.

[0165] In FIG. 25 the figure of the left shows the cardboard, plastic, rubber or alike in a cut condition with the folding lines shown in sketch or interrupted lines. In this example, the main body may have a substantially rectangular shape and the folding lines may comprise parallel lines (230) in the direction of the longer sides of the rectangular shape and parallel lines (231) in the direction of the shorter sides of the rectangular shape thus defining a plurality of small squares. The folding lines may further comprise parallel diagonal lines (232) traversing vertices of the squares. The figure of the right shows some folding lines in a folded condition to form the lids (110, 120) and lines (230) folded to form part of the main body. Glue or other adhesive may be used to put together the side ends of the main body and lines in a folded condition forming the lids. Instead of glue, other components may be added to connect the side ends of the main body with elements such as zips, male-female connectors, magnets, pressure fitting, friction fitting, snap fit connectors, clip connectors, latches, buckle connectors, electronic connectors, biometric or other password locks of any kind, rubber connectors, threads, clamps or other mechanical-based connectors, e.g. Velcro.

[0166] FIG. 26 shows the travel bag of FIGS. 11c and 25 with a mat (200). The sequences of figures from left to right show the steps for folding the mat and introducing it inside the bag to get ready for transport. The first step starts with the bag in the compressed configuration and may comprise rolling up the mat (200). Once the mat is rolled up, the second step may comprise opening the first lid (110) and starting expansion of the main body by unfolding lines (231) and (232). When the main body (130) is an intermediate configuration between compressed configuration and the extended configuration, the third step may comprise introducing the folded mat (200) inside the elongated storage housing defined in the intermediate configuration. The last step may comprise completing extension of the main body and closing back the first lid (110).

[0167] FIG. 11d shows the example of FIG. 1a or FIG. 6 in the extended configuration in which the handle system has been removed. In this example, the rod (138) describing a substantially helical shape provided around the flexible and foldable material may be provided in combination with joint means, e.g. a channel (139) formed by sewing a portion of a flexible material to provide housing for the rod (138). The rod (138) inserted in the channel (139) is also shown in the cross-sectional view of FIG. 15. The channel (139) may be continuous along the rod (138) or only locally provided along stretches.

[0168] The example of FIG. 11e differs from that of FIG. 11d in that two rods (138) may be provided describing substantially helical shapes in opposite directions so as to create crossings (1381) between the two rods (138). In alternative examples, instead of rods a cable or other rigid and bendable material may be used.

[0169] FIG. 11f shows an example of travel bag in which the main body may comprise two stripes or bands (137) made of an elastic material. Such elastic material may be capable of returning to its original length and shape due to its nature or may be deformed and extended as a result of gravity, due to the load of the lower lid (120). The bands may extend longitudinally to connect the first (110) and the second (120) lids to define the extended configuration. In alternative examples, other number of bands may be foreseen.

[0170] In all cases, an outer surface of the lids may comprise texts, diagrams, drawings, patterns, bar codes, QR codes or any type of logistic and reference code, logos, colours or textures.

[0171] FIGS. 12a-12d show different ways of carrying a travel bag substantially as hereinbefore described in the extended configuration by a person.

[0172] In the example of FIG. 12a a length of the belt (154) may be adjusted such that the bag may be carried as a bandolier.

[0173] In the example of FIGS. 12b and 12d the belt may be adjusted (e.g. through the rings 169) as a waist strap (167) and may be provided with an extension (1671) to add stability.

[0174] Alternatively, a strap or grip (168) to the leg may further be provided.

[0175] In the example of FIG. 12c the belt may be replaced by two straps or ropes (166) such that the bag can be carried as a back-pack.

[0176] All these examples allow a hands free transport of the bag.

[0177] In all cases, the handle system may be folded inside the lids in the compressed configuration or may be fully removable while in such a compressed configuration.

[0178] FIGS. 13a-13b show different ways of carrying examples of a travel bag substantially as hereinbefore described in the compressed configuration. In these examples, the lids (110) and/or (120) may be provided with fastening elements such that the belt (or strap) (154) used to carry the bag in the extended configuration can be adjusted to an outer surface of one or more of the lids (110) and (120). Mechanical joints such as clips, Velcro o buttons (156) may be foreseen. The compressed configuration can thus become a traditional hanging bag as shown in FIG. 13a). Alternatively, the belt or strap may be replaced by handles (164) to transform the travel bag into a grab hand bag as shown FIG. 13b

[0179] In all these cases, only shown in FIG. 13b, one or more of the lids may comprise one or more external pockets (118). The pocket (118) is also shown in FIG. 15 although in the example of FIG. 15 the pocket may be located inside the lid.

[0180] In the example of FIG. 16 one or more supplemental storage compartments (180) may be provided in any one of the main body (130) or the first (110) and second (120) lids, or combinations thereof. These compartments (180) may be suitable for carrying personal objects of the user such as mobile phones, purse or keys. Other uses may also be foreseen.

[0181] FIG. 17 shows a top view of any of the lids (110 or 120) that may be provided with an internal pocket (118) with its own closure system (119). In more examples, other number of internal or external pockets may be foreseen. In yet more examples, some of these pockets may be removably arranged, i.e. they may be stuck to an outer surface by e.g. Velcro. In other examples, the pocket may be permanently arranged.

[0182] FIGS. 14a-14f show examples of locking systems for the lids of a bag of FIGS. 1a, 4, 6 o similar in the compressed configuration, i.e. locking systems between the first (110) and second (120) lids. As a general rule, the locking system may be visible or not depending on its own design. Examples of visible locking systems are provided in FIGS. 14a-14d and examples of invisible locking systems are provided in FIGS. 14e and 14f. Other alternatives may also be foreseen.

[0183] In the example of FIGS. 14a and 14b, the locking system may comprise a button/eyelet coupling 156 in combination with one or more bands (171). The bands (171) may be sewn (152) to the lids or they may be separate. In the example of FIG. 14c the button coupling (156) may be tied with a cord (176) or similar. In the example of FIG. 14d the locking system may comprise an elastic band (173) that may be arranged around the two lids (110) and (120) being brought together. In this example, the elastic band (173) may have a further use (in combination with the transport of a mat). It may be used as a resistance band for the practise of yoga or pilates. The button coupling (156) is also shown in the cross-sectional view of FIG. 15.

[0184] In the example of FIG. 14e, the locking system may comprise a matching thread at each open end of the first (110) and second (120) lids. And, in the example of FIG. 14f, the locking system may comprise a pair of magnets (174) at each open end of the first (110) and second (120) lids.

[0185] FIG. 18 shows an example of a hanger element that may be provided in any of the lids (110 and/or 120) of a travel bag substantially as hereinbefore described. In an example, the hanger element may be a hook (124) that may be hidden inside the outer closed end of any of the lids (110 or 120). To hide the hook (124) a rotatory notch/cover (122) (or notch with cover) may also be provided. FIG. 18 further shows a sequence from left to right showing how the hook (124) may be extracted. The sequence starts with a closed end of the second lid (120). The notch/cover (122) is rotated (see arrow N1) so as to discover the hook (124). In the next step, the hook (124) is pivoted upwards (see arrow N2) so as to become unfolded.

[0186] FIG. 19 shows a rolling garment sheet (191) that may be used to fold a garment. The sheet (191) may be rectangular. In more examples, the sheet may have a shape equal or similar to that of the garment to be wrapped, e.g. jacket, shirt, suit, dress. The rolling sheet may be made of a flexible or continuously bendable (in at least a primary rolling direction) material. Alternatively, it may be provided with a plurality of folding lines arranged perpendicularly to the primary rolling direction. In the example of FIG. 19, a method of storing a suit (193) inside a bag substantially as hereinbefore may further be explained. The sheet (191) may be arranged horizontally, the suit (193) may be provided on top of the sheet (191) and the arrangement sheet-suit (191+193) may be rolled-up to define a tubular body that may be fitted inside a bag (shown in broken lines) substantially as hereinbefore described. This packing system can reduce wrinkling of the garment. This packing and transportation of the garment may be of special interest e.g. in case of travelling with jackets by plane or at in hot climates where the garment can be carried in the travel bag before a meeting and then wear it upon arrival and juts during the event, ensuring or at least enhancing the possibility that there are no wrinkles: At the same time, saving space as the compressed configuration of the travel bag may be used as an elegant small accessory substantially as hereinbefore explained.

[0187] FIG. 20 shows a further example in which the rolling sheet (191) may be combined with a rolling guide. The rolling guide may be provided with a clipping system to fasten a garment to be rolled-up while it is being rolled-up. The clipping system may comprise two bars or rods (197) and (196) that are separable (see broken lines) from each other thereby fixing the suit (193) to be wrapped. In more examples, the two bars may be replaced by one or more clips or two fixed bars at one end. The provision of two bars enhances the ironing effect of the rolled condition in a garment.

[0188] In some cases, as shown in FIG. 20, the rolling sheet (191) may further comprise fastening members (195) to firmly secure the suit (193) while it is being rolled-up.

[0189] In some cases the garment rolling sheet is flexible or continuously bendable in at least a primary rolling direction or is provided with a plurality of folding lines arranged perpendicularly to the primary rolling direction. In other examples the rolling sheet is rigid or semi-rigid so as to be self-held in a tubular form once it is rolled-up. In further examples the garment rolling sheet is rectangular or has a shape substantially equal to that of a garment to be wrapped, while in other examples the rolling sheet further comprises fastening members to firmly secure a garment while allow rolling of the garment.

[0190] In more examples, a cover may be provided on top of the garment to further protect it while being transported. In more examples, the sheet may comprise one or more cut-outs through which the garment to be rolled-up can be at least partially inserted. And in yet more examples, a motor may be provided to automate the rolling of the sheet, similarly to rolling window shades or projection screens.

[0191] The rolling guide may be made of bamboo, paper, metal paper, cork, carbon fiber, nylon fiberglass, polyester, polymers, leather, graphite, cotton or other fabrics, foam, cardboard, plastics, rubber, thermos-formable materials, elastomers, shape-memory alloys, aramid fibers, aluminium and other light metals, recycled materials, biodegradable materials, jute, composites or aerogels.

[0192] FIG. 21 shows an example of the garment rolling sheet with the suit being inserted (see arrow B) into a travel bag substantially as hereinbefore described. In this example, one of the lids may be provided with a hanger element (199) that may be fixed or removable. Velcro, clips, hook-and-loop string or any other closing system may be foreseen for ensure locking of the packed suit.

[0193] The example of FIG. 22 differs from that of FIG. 1a, 4 or 6 in that the lids (110 and 120) may be compacted, i.e. a distance between an open end and a closed end of each of the lids (110 and 120) may be minimal, or they may even be virtually coincident. In these examples, an outer surface of the closed end of the lids (110 and/or 120) may comprise elements such as a mirror, note pad, digital screen or an area to expose inspirational, marketing or logistic features such as texts, diagrams, textures, drawings, patterns, bar codes, QR codes, logos or colours.

[0194] FIGS. 23a-23f show examples of travel bags in the extended and compressed configurations showing different alternative uses of the compressed configuration. These examples differ in the way the lids are built or fitted to allow any of this or other use.

[0195] In the example of FIG. 23a at least one of the lids may be provided with an incense burner (116) as explained in connection with FIG. 1a. In the example of FIG. 23b, at least one of the lids may be provided with a speaker (302).

In the example of FIG. 23e at least one of the lids may be made rigid enough to be used as a seat (308). In the example of FIG. 23f at least one of the lids may be made of foam or cork to provide a yoga-pilates block usually used in the practise of these activities.

[0197] FIGS. 24a-24d show examples of the travel bag of FIG. 4 or 7 in the compressed configuration. In the example of FIG. 24a, a portion of the outer surface of the main body may be used as a notepad (314) in a similar manner as explained in connection with FIG. 4. This configuration may also function as a bag for articles that are smaller than the elongated article to be carried in the extended configuration. In the example of FIG. 24b this portion of the outer surface may be used to show a text or drawings. FIGS. 24c and 24d show alternative uses of the ropes or cords or bands use to close the bag in FIG. 1b, 4 or 7. In FIG. 24c a jumping rope (318) is shown and in FIG. 24d a resistance band (319).

[0198] In some examples, the main body may be made of transparent or translucent materials. FIG. 29 shows examples of bags having a main body that is at least partially made of a transparent or translucent material. In these examples, the portion of the main body made of a transparent material is denoted with numeric reference (133) whereas the portion that is made of an opaque material is denoted with numeric reference (132). A locking system (320) may further be provided. The locking system (320) may be configured to authorize or control the opening of the bag.

[0199] In some examples, the locking system may comprise any of biometric locks, digital, electronic, magnetic, mechanical password locks or near-field communications.

[0200] In these examples, the bag may further solve a problem of displaying garments in reduced size stores as the garments may be displayed in a rolled condition hung from a relatively small display. FIG. 30 shows an example of a plurality of bags containing, e.g. a suit, being displayed in a hung condition from a clothing rack. A mannequin may be provided on top of the clothing rack wearing the garment that represents the style of the rest of the garments packed and displayed in the rack. This way the actual cloth, its texture and design can be exhibited without the need to take out the garments from the bags.

[0201] FIGS. 27 and 28 display traditional set-ups for selling yoga-mats and garments respectively.

[0202] FIG. 31 shows a flow chart of an example of a method of displaying or storing yoga mats being placed in a travel bag substantially as hereinbefore described. The process starts at step (201) with a travel bag according to any of above examples and a yoga-pilates mat to be rolled up and store within the bag. The yoga mat is laid flat. At step 202 the yoga mat is rolled up. At step (203), the rolled yoga mat is inserted into the bag (see e.g. FIG. 6, 7 or 26). At this point, examples of the storing process may comprise e.g. accommodating the bags in a horizontal configuration in rows, one next to the other and a row above the other and examples of a displaying process may comprise hanging the bags from a display rack.

[0203] FIG. 32 shows a flow chart of an example of a method of displaying garments being placed in a travel bag substantially as hereinbefore described. The process starts with a plurality of travel bags according to any of above examples and a plurality of garments, e.g. suit, shirts, dresses, jackets, to be rolled-up and stored within the bag. The first step (301) involves laying a garment rolling sheet substantially as hereinbefore described in an extended condition, i.e. substantially flat (see FIG. 20). At step (302) a piece of garment is laid flat on the rolling sheet. After this, two optional steps may follow, either alone or in combination. In a first optional step (303), the piece of clothing is secured to the garment sheet to prevent the clothing from slipping off or moving while rolling up. And/or in a second optional step (304), the rolling sheet is secured to a rolling guide to ensure the clothing is properly rolled-up (see FIG. 20). At step (305) independently from steps (303) and/or (304), the piece of clothing and garment rolling sheet are rolled-up to form a tight roll to prevent wrinkling and other deformations of the clothing. At step (306), the rolled garment and sheet are inserted into the bag (see e.g. FIG. 21). At this point, examples of the displaying process may comprise hanging the bags from a display rack. The disclosed displaying method involves that each piece of clothing is previously stored within the bag and then the plurality of bags housing the pieces of clothing is hung from the display rack.

[0204] In some examples, as explained before, the bags with the mats or the pieces of clothing may be locked or sealed.

[0205] Turning now to FIG. 33, it shows a longitudinal section of the bag (100) through the storage cavity of three bags modules, the first bag module (130) or main body, the second bag module (2020) and the third bag module (2010).
